About the Game
A box, fully packed edge-to-edge with polycube pieces...no gaps, no wasted space. Every piece has an arrow stamped on it, showing the one direction it's allowed to travel. Tap a piece and it only comes free if there's a clear path to slide it all the way out along that arrow; if a neighbor is in the way, it stays put. Clear the box by working out the order: which piece has to leave first so the next one can follow, all the way down to an empty box. Rotate your view to check a blocked piece from every angle...the box itself never moves, only how you're looking at it.
Ways to play
- Campaign: A hand-baked ladder of thousands of boxes, from a snug 3×3×3 up to a sprawling 7×7×7, each size split into an easy and a hard tier so the challenge ramps twice: once as boxes grow, once within each size. Every box opens instantly; no waiting on a puzzle to generate.
- Free Play: Pick your own box size and piece size and get a freshly generated puzzle every time. No two boxes alike, no pressure to progress a ladder, just pull up a board and go. Endless play without using lives.
- Daily Challenge: One box, the same for every player, every day. Come back tomorrow for a new one.
Features
- Full 3D polycube puzzles from 3×3×3 up to 7×7×7, each piece constrained to a single slide-out direction
- A campaign with thousands of difficulty-ordered levels, split into easy and hard tiers per box size
- Free Play with fully custom box and piece sizes, generated on demand
- A daily challenge board shared by every player
- Undo and hints when a box has you stuck, plus a mistake counter to track a clean run
- Stepped isometric rotation to inspect a box from any angle without ever moving the pieces themselves
What Makes It Different
Every piece has a direction.
It's reasoning about which pieces block which, in three dimensions, where a wrong pull just means the piece won't move at all. The puzzle is entirely in the order.
A ladder that actually ends somewhere.
Thirteen box sizes, each with its own easy and hard tier, baked ahead of time so there's no generation lag between one solved box and the next. It's a real campaign, not an endless random shuffle.
Fair, not pay-to-win.
Lives regenerate on their own over time, and a rewarded ad or a one-time purchase just gets you back in sooner. Free Play never touches your lives at all.

CubiClear is a 3D polycube puzzle where clearing a box means figuring out which order every piece can slide free. Available now on Android, iOS coming soon.
Long
CubiClear is a 3D slide-out puzzle game: a box is packed edge-to-edge with polycube pieces, and every piece carries an arrow showing the single direction it's allowed to travel. A piece only comes free if the path along its arrow is clear, so clearing the box comes down to working out the right order to pull everything.
Campaign mode offers a hand-baked ladder of thousands of levels across thirteen box sizes, from 3×3×3 up to 7×7×7, each size split into easy and hard tiers. Free Play generates a fresh puzzle to your own chosen box and piece size, and Daily Challenge gives every player the same board once a day. Undo, hints, and a mistake counter help newer players, while a stepped isometric view lets anyone inspect a stuck box from every angle.
Monetization is ad-supported and convenience-only: lives regenerate over time, and ads or an optional purchase just speed that up. Available now on Android, with iOS coming soon.
